BACKGROUND: To examine the relationship between hepatitis C virus (HCV) infection and diabetes mellitus (DM) in Japanese populations, a retrospective study was done in 866 patients with chronic viral disease. METHODS: The present study included 707 HCV-infected and 159 hepatitis B virus (HBV)-infected patients. The prevalences of HBV- and HCV-related cirrhosis were 32% and 33%, respectively. A case-control study was also conducted to determine the seroprevalence of HCV infection in a cohort of 459 diabetics. RESULTS: The prevalence of DM was higher in HCV-infected patients (20.9%; P < 0.02) than in HBV-infected subjects (11.9%). In the cirrhotic patients, DM was observed in 30.8% of the subjects with HCV compared with 11.8% of those with HBV ( P < 0.01). Multivariate analysis revealed that the major independent variables associated with type II DM were male sex (odds ratio, 1.54; p = 0.020) and cirrhosis (odds ratio, 1.97; P = 0.0007). The relative odds of the development of DM were calculated to be 3.2 times higher in HCV-infected cirrhotic patients than in HBV-infected ones. In the case-control study of the diabetic cohort, 10.5% of patients were infected with HCV compared with 1.1% with HBV ( P < 0.0001). The results indicate that HCV infection is closely associated with DM, compared with HBV infection. Cirrhosis was an independent risk factor for DM. CONCLUSIONS: Taken together, the findings indicate that cirrhosis appears to be a more important predictor of glucose intolerance than HCV infection, and the combination of both factors increases the risk of DM in our populations.
